Understanding energy changes is very important for chemical engineers. Here’s why:
Reaction Types: There are different kinds of chemical reactions.
Some reactions release energy. These are called exothermic reactions. An example is when methane burns.
Other reactions take in energy, which we call endothermic. A good example of this is photosynthesis, where plants turn sunlight into energy.
Enthalpy Changes: Enthalpy is a fancy word that measures energy changes in reactions.
When we see a negative change in enthalpy (ΔH), it means energy is being released, and the reaction is exothermic.
If the change is positive, it means energy is being absorbed, so the reaction is endothermic.
Process Optimization: Knowing how energy changes work helps engineers create safer and more efficient ways to do things in factories.
In short, understanding these ideas helps chemical engineers design processes that are better, safer, and more efficient.
